wp-20 torch, DIN adapter, water cooling set up?

admin

I have a Lincoln 175 square wave TIG. I recently bought a WP20 torch and the dinse adapter (gas through) so I could use the WP20 on my machine. I bought the adapter the guy at the local welding store (Air Gas) said I would need figuring he has seen this situation before. I am now thinking that this is the wrong adapter. Either that or I have no idea how to set this thing up.Also, I'm making my own water cooler. It will be external and completely separate from the welder. Here's a pic of the disne adapter and my torch. How would I go about setting this thing up?Lincoln Square Wave 175 TIGLincoln 110v flux core welder (my 1st)Clarke 180EN MIG

Reply:After looking at the diagram again, I realize that it will not work like that. There would be no outlet for the water to recirculate. I think that the gas would flow through the center of my din adapter and into the power cord.Last edited by sen2two; 11-25-2010 at 11:05 AM.Lincoln Square Wave 175 TIGLincoln 110v flux core welder (my 1st)Clarke 180EN MIG
Reply:IIRC the gas and water lines have different threads so it should be hard to mix them up..No government ever voluntarily reduces itself in size.

Reply:The red line coming from the adaptor is the coolant return line to the cooler. The black line from the adaptor hooks up to the gas line to the torch using a male-to-male adapter. It is on of the 2 smaller black line to the torch. Probably the easiest (for me) way to tell which of them is the gas line is to blow through each of the ends while feeling for air coming out of the nozzle of the torch. The other small black hose goes to the out-to-torch fitting of the cooler.As said before though,the fitting threads are different: the gas hoses have right hand threads and the coolent lines have left hand threads.Last edited by PeterTrocewicz; 11-25-2010 at 02:05 PM.

Reply:The original flo thru dinse is used for air cooled torch.It has no hoses. Argon and power are in same cable.When you go to a water torch the gas goes into dinse from welder and out of dinse to torch through its own line not through power cable like air cooled.The argon flows out of welder "into" dinse "out" of dinse with black hose that connects to torch gas "in" hose shown in pic. r/h thread. What is "not" shown in the pic is the water supply to torch which you will hook directly to cooler not welder. The red line is the warm water return from torch water and power cable that are together this is the larger cable.Only one line left which is water supply from cooler. Not that complicated.
Reply:I know this thread is a couple years old but it popped up while I was searching to resolve this very same problem, I found an alternative answer to the one provided so I thought I would post it for others searching as well.The ADAPTER needed to connect the water cooled tig torches (18 & 20) to lincolns Twist mate connector with gas pass through is lincoln part number K1622-4 found HERE, its in pdf format.
